ST. LOUIS, Mo. — BJC Health and Aetna have agreed to a one-year transition period for Illinois state retirees enrolled in the TRAIL Aetna Medicare Advantage plan, according to a November 6 letter reported by First Alert 4.

The agreement allows those retirees to continue receiving covered care through BJC during the 2027 calendar year while they consider future coverage arrangements.

The limited agreement follows BJC’s announcement that its Aetna Medicare Advantage contract would end December 31. It does not establish a general extension for every Aetna Medicare Advantage patient or plan.

BJC said it would consider similar arrangements with other group plans, but the reported letter did not announce additional agreements. Patients should distinguish the Illinois state-retiree provision from the broader contract dispute.

Medicare’s annual enrollment period ends December 7. The organizations’ current notices and individual plan documents remain the sources for determining whether particular coverage is affected.
